A seal ring has a central axis and an elastic ring member made of elastic material and an annular body portion and a flange surrounding the annular body portion. The thickness of the flange is smaller than the thickness of the annular body portion as measured in the axial direction of the seal ring. A hose connector assembly includes the aforementioned seal ring.

A fuel quick connector body according to various aspects of the present disclosure includes a wall. The wall extends along a longitudinal axis between a first end and a second end. The wall defines a passage between the first end and the second end. The body includes a polymer. The polymer includes polyphenylene sulfide in an amount greater than or equal to about 70 weight percent. The polymer may have a flexural modulus of less than or equal to about 4 GPa. The polymer may have a notched ISO impact strength of greater than or equal to about 25 kJ/m.sup.2. The polymer may have an elongation at break of greater than or equal to about 15%. In various aspects, the present disclosure provides a fuel quick connector including the fuel quick connector body, a retainer component, and an O-ring.

A connector for connecting pipes for transporting fluids has a tubular casing, which extends around a main axis; an end insert, which can be snap coupled to one end of the tubular casing; a tubular sleeve, which is configured to be fitted around a respective fluid transport pipe and to cooperate with the end insert such that a relative rotation around the main axis of the tubular sleeve within the end insert results in a relative displacement of the tubular sleeve with respect to the end insert in a direction substantially parallel to the main axis; and a clamping element, which is housed within the tubular casing and is configured to retain the respective transport pipe.

A method and apparatus for assembling a high purity liquid distribution system is described. A distal end portion of the tube is heated then pushed over a sleeve so that the distal end portion can have a shrink seal fit over the sleeve to mitigate accidental or inadvertent pull out of the tube from a fitting. Other benefits are also achieved such as minimal flow restriction of the liquid flowing through the joint and the tube.

A fluid transfer connector securely connects a port fitting of a fluid device to a fluid hose. The fluid transfer connector includes an attachment member attachable to the port fitting of the fluid storage device. The fluid transfer connector further includes a hose adapter including a housing with a seal that wipes and sealingly engages the port fitting when the hose adapter is engaged to the attachment member.
